Abstract: This invention provides a method applied for the new dynamic arc radiotherapy treatment planning to calculate an optimal arc angle. With this invention, an operator without rich experience is able to reach the expected low dose in lungs easily and quickly. This invention can not only estimate the distribution of low radiation dose in lungs but also reduce the shortcomings like consumption of time and inaccuracy caused by manual trial and error.

Abstract: A system of mapping a cardiac image of single heart chamber and a method thereof are disclosed. In the system and method thereof, one heart chamber (such as a left atrium, a left ventricular, a right atrium, right ventricular or aortic structure) can be selected in a 3D-based cardiac image (such as a CT or MRI image), and slices of the selected heart chamber are reconstructed and unwrapped by a 2D mapping visual display manner. The visual display and required angle alignment planes for subsequent analysis will be adjusted and achieved by operator manually, with specific global and regional architectural analysis performed by automatic algorithm.

Abstract: The invention provides a method for quantitative analysis of nuclear medicine brain imaging. The method comprises retrieving a target image, wherein the target image is a brain image as a nuclear medicine image produced from a radiopharmaceutical, then matching the position of a space axis and the size of a voxel of the target image to a standard template by an affine transformation, wherein the standard template comprises a relative position of striatum. The method further comprises selecting the striatum from the target image according to the relative position of the striatum in the standard template and calculating an average value of the striatum, dividing the striatum from the target image and calculating a background value based on a remainder pixel value of the target image, and a specific uptake ratio is calculated based on the average value of the striatum and the background value.

Abstract: A method for metallizing a non-metallic surface includes plating a basic metallic plating film on a non-metallic surface, plating a first metallic material on a surface of the basic metallic plating film to form an inner metallic layer, and plating a second metallic material on a surface of the inner metallic layer to form an outer metallic layer. Thus, the thin basic metallic plating film is previously plated on the non-metallic surface in a vacuum sputtering manner, so that the non-metallic surface is electrically conductive, thereby decreasing the working time of the later chemically or electrically plating steps, and thereby enhancing the productivity.

Abstract: The present invention relates to an interface connector for protecting against electromagnetic interference. The interface connector includes a layer of insulating coating of mylar or other heat-resisting polyester. An elastic flexible portion is formed by wrapping the insulating coating at the center or at least one end thereof. In addition, the layer of insulating coating has metal sputter coating against magnetic discharge. The metal coating after sputtering treatment is uniform in thickness and pore-free so that the impedance of the whole surface is consistent to effectively protect against electromagnetic interference between the external and the self-producing electromagnetic waves. Furthermore, it's not required to wrap the conducting adhesive tape so that the processing procedure can be simplified and the production cost can be reduced.
